Abstract (en)
A method for manufacturing a hot-dip metal plated steel strip having a plated layer formed on the outer surface thereof includes continuously immersing a steel strip in a bath tub that accommodates a molten metal plating bath, causing a sink roll disposed in the bath tub to change the traveling direction of the steel strip, then causing the steel strip to pass through two support rolls formed of a stabilizing roll and a correcting roll disposed above the sink roll but below the surface of the plating bath, and extracting the steel strip out of the bath. A flow regulation plate is disposed so as to cover at least the upper side of a roll body of the stabilizing roll out of the support rolls with a gap between the flow regulation plate and the stabilizing roll, and the flow of the molten metal plating bath directed toward a portion of the steel strip located from the exit of the support rolls to the surface of the plating bath is led toward the lower side of the stabilizing roll via the gap.
